Restore support for local class literals in annotation arguments

This was broken in c1ab08c8ce where we started to represent KClassValue
as a ClassId of the referenced class + number of times it's been wrapped
into kotlin.Array. Local classes do not have a sane ClassId, so in this
change we restore the old behavior by representing KClassValue with a
sealed class value instead
